I. 0. SILVER 

by Brad Wilhelmsen 



INTRODUCTION 

I. O. SILVER is a hi-res strategy/arcade game for the Apple II series of 
computers. Dr. I. 0. Silver is a semi-world famous hi-res scientist and 
renowned hardware nut. The Professor is forever attempting to build the 
new fifth generation "Super Computer" from the array of integrated circuits 
(computer chips) on the Apple screen. Your job is to help him out. 

HARDWARE REQUIREMENTS 

The only hardware required to play I. 0. Silver is any version of Apple II 
and a disk drive. Well, o. k., you do need a monitor — a color monitor will 
add color to the game, but a non-color screen will work just as well. If you 
have a monochrome monitor (green screen, black-and-white, etc.), you can 
discern the different colors by the patterns on the playing pieces. Whenever 
we refer to "color" in these instructions, we also mean "pattern". 

You can play the game using only the keyboard (our favorite way), but a 
joystick is an optional accessory (and besides, after a few years, if you tire 
of the game, the I. 0. Silver disk and a joystick can be used for a rousing 
game of floppy ring toss). 

BACK IT UP 

In keeping with Beagle Bros tradition, the I. 0. Silver disk comes from the 
factory unlocked and unprotected. "Unlocked" means that if you're into 
machine language — or would like to be— you can inspect or change the 
game to see what makes it work. "Unprotected" means you can copy the 
disk with the standard Apple copy program that came with your Apple. 
That way if your original disk fails (or falls into the fish tank), you've got a 
replacement. Make a backup of the disk now; we'll wait here. 

US CRAZY? NO WAY, JOSE! 

Selling a copyable game disk is considered by some in our industry to be 
what's known as— in business terms — a "dumb move". We heartily 
disagree, and believe that making software more friendly makes it a more 
valuable product to you, our valued customer. Please support our efforts by 
not giving copies away to your friends. Every illegal copy you see or use is 
a vote FOR copy protection and AGAINST friendly software. You support 
us, and we'll support you. 

SOURCE CODE AVAILABLE 

Some of you advanced programmers might be interested in obtaining the 
source code for I. 0. Silver. If so, check the Appendix (page 20).

The Object of the Game 

GET RICH BY PUSHING CHIPS! 

The object of I. 0. Silver is to move the Professor around the screen and 
push together all of the chips of the same color, thus combining them and 
creating other parts which ultimately create a Super Computer. For each 
Super Computer built, you get a hi-res medal and tons of imaginary cash. 

Short of that lofty goal, the object is to survive and earn as much money 
as possible by combining as many chips and other computer parts as you 
can. High scores are saved on disk at the end of each game. Besides 
getting the all-time highest score (and becoming famous), there is no way 
to actually "win" the game. 

DE-BUGGERS WANTED 

You will work within a one simulated-year deadline and constantly be 
harassed by a gang of computer "bugs" which will try and rob you of your 
most valuable asset— time. You can, however, earn even more money by 
trapping these pesty critters. 

TWO WAYS TO PLAY 

You may play two different versions of I. 0. Silver— the high-pressure 
"ARCADE WORKSHOP" or the take-your-time "STRATEGY LAB". See 
page 6 for details.

Summary of Game Controls 

KEYBOARD MODE— 

I, J, K or M: Moves or turns the Professor, OR pushes (if not blocked) the 
adjacent chip that the Professor is facing— up, left, right or down. 

CONTROL-C: Lets you change from I/J/K/M to another set of keys. 

CONTROL-A: Switches to joystick (instead of keyboard) control during the 
game. You may adjust your joystick when the switch is made. 

JOYSTICK MODE- 
JOYSTICK STICK: Moves or turns the Professor in the direction selected. 

JOYSTICK BUTTON (either one): Pushes (if not blocked) the adjacent 
chip that the Professor is facing. 

CONTROL-C: Lets you adjust your joystick for proper centering. 

CONTROL-B: Switches to keyboard (instead of joystick) control during the 
game. You may optionally change from I/J/K/M to another set of 
keys when the switch is made. 

BOTH MODES- 
CONTROLS: Toggles the sound on and off during the game. (Remember, 
if you have an Apple with a volume control, be sure the volume is not 
all the way down if you want sound.) 

ESC: Ends the current level (Note: The Arcade Workshop version requires 
at least as many execution points as the level number to end a level — 
page 13). 

RETURN: Lets you take a vacation and study the screen to plan your next 
set of moves (Arcade Workshop only). 

CONTROL-RESET (not recommended): Stops everything in its tracks and 
forces you to re-boot a disk.

Summary of How to Play I. 0. Silver 

(The small numbers like " 1S " are page references for more information.) 
GETTING STARTED— 

■ BOOT THE DISK by inserting it in your main drive and turning on 
your Apple. You will see the Disk Menu with its I, and S options. 6 

■ PRESS "I"— You will soon see the game's Title Screen. 

■ PRESS ANY KEY when the drive stops— You will see the main menu. 6 

■ PRESS "1" to play the Arcade Workshop version 6 of the game (or select 
one or more of the other options). 6 You will see the chip values. 8 

■ PRESS ANY KEY and you will see the Laboratory (playing screen. 9 ) 

PLAYING THE GAME— 

Some Rules Before You Start: I. 0. Silver is played on advancing "levels" 13 
numbered from 1 to 26. You have a one year time limit on each level, 
indicated by the calendar 9 at the top of the screen. If time runs out, it costs 
you one Professor. 13 You are given three Professors to start the game (you 
only play with one at a time). 

■ PRESS ANY KEY to release the bugs and begin playing the game. Move 
the Professor 11 , dodging the bugs as much as possible. Push the chips 11 to 
combine as many of the same color (and pattern) as you can. When all the 
chips of one color are combined, they become a "circuit board", 12 which 
may be combined to create other parts, 12 which ultimately, if you're good 
enough, will combine down to become one object— the Super Computer, 
earning you a well-deserved medal and the biggest prize money. 

Each chip combination and new object created (like a circuit board) 
earns you money. You may also trap bugs 15 between chips to earn more 
money and, at least temporarily, get them off the screen. 

Creating any new part (like a circuit board) gains you one or more 
"execution points". 13 If the number of execution points equals or exceeds 
the current level number, you may press ESC and go on to the next level, 13 
where you will start over with a new batch of chips. OR you may continue 
earning money by building on the current level. 

If time runs out (on DEC.31), the level will end and you will get to 
replay the same level (unless you have used all three of your Professors; 13 
then the game is over). 

Your earnings and the number of Professors remaining will be reported 
between levels in an "annual report". 16 High scores and in-progress games 
may be saved on disk. 18

Features of the Game 



■ THE DISK MENU 

This menu will appear when you turn on your Apple to boot the disk: 

(I) PLAY I. 0. SILVER 

(0) OTHER STUFF 

(S) STOP FOR NOW 
"Other Stuff' is self-explanatory; try it sometime. "Stop for Now" is rather 
boring and not recommended. PRESS THE "I" KEY to play I. 0. Silver. 

■ THE MAIN MENU 

When you see the game's title screen and the disk drive stops, 
PRESS ANY KEY and the following list of options will appear: 

1. ARCADE WORKSHOP 

2. STRATEGY LAB 

3. SEE HIGH SCORES 

4. SEE SAVED GAMES 

5. SELECT JOYSTICK (or ADJUST JOYSTICK) 

6. CHANGE KEYS (or SELECT KEYBOARD) 

7. SOUND: ON (or SOUND: OFF) 

8. TV: COLOR (or TV: MONOCHROME) 

9. QUIT 

At this point you may simply PRESS "1" OR "2" to play the game, or 
make adjustments by selecting one or more of the other options. Following 
is an explanation of all the Main Menu options. 

Options 1 and 2 — 

Select one of these two options (press "1" or "2") to start playing a game. 
You decide which of these two versions of I. 0. Silver is for you: 

ARCADE WORKSHOP 

This version of I. 0. Silver has more action. It is also more pressure- 
packed, since you are given a firm deadline and a room full of "bugs" 
that are out to zap you and bring that deadline even closer. 

STRATEGY LAB 

This version of I. 0. Silver puts no time limit on you — you can take all 
day to make a move — and bugs are prohibited. After trying the game 
both ways, the Strategy Lab may be the only version you want to play. 
Or you may want to use it to practice or to plan an attack that can be 
used in the Arcade Workshop, (see page 18 for more details) 



6 



Option 3— SEE HIGH SCORES 

This option lets you look at the highest Arcade Workshop scores (if any) 
that have been saved on the disk that is currently in your main drive. 

Option 4— SEE SAVED GAMES 

This option lets you see a list of up to ten in-progress Arcade Workshop 
games that were saved (by you) on disk. You can select one of these games 
(thus removing it from the disk), if any exist, and continue playing it at 
the point from which it was saved. 

Option 5— SELECT (or ADJUST) JOYSTICK* 

This option lets you control the game with a joystick (instead of the Apple 
keyboard), or adjust it if it's already selected. (When the disk is first booted, 
the keyboard is automatically the controlling device.) 

Option 6— SELECT (or CHANGE) KEYBOARD* 

This option lets you play with the keyboard (instead of a joystick). If the 
keyboard is already selected, you may use this option to change the keys — 
I, J, K and M — that control the game. (Beagle Bros is not responsible for 
injuries suffered when using the I/J/K/M configuration.) The four arrow 
keys (found on some Apples) are an obvious, but BAD alternate key choice, 
we think, because of the way they are positioned on the keyboard. You 
might like to try two-handed operation by choosing A & Z (up & down) 
and the left & right arrows (left & right). 

Option 7— SOUND: ON (or OFF)* 

To toggle the sound on and off, press the "7" key. If you hear a tone, I. 0. 
Silver will be played with a variety of beeps, buzzes and music. Don't 
forget — if your Apple has a volume control, turn up the volume. 

Option 8— TV: COLOR (or MONOCHROME) 

If you select Monochrome, the game will simply be played with more 
contrasting colors. Both versions work with both kinds of monitors. 

Option 9— QUIT 

This option will let you boot a disk. 

* You may also control this feature while the game is running. 
See SUMMARY OF GAME CONTROLS on page 4.

Chip and Bug Values 



Before each level begins, you will be shown the values for combining chips 
and trapping bugs. The screen will look something like this: 



1 .0, SILUER. 
5 $2,588 



LEUEL .81 

shiiie

TIRE BOHUS • $258 PER DAY 



$1,888 



■to* 

$2,888 



$3,888 
PRESS ANY KEY 



$4,888 



At the top right is the upcoming level number. Under that are the six 
different color chips and the values that will be obtained by combining two 
chips of that color. The "De-Bugging Bonus" is the amount earned if you 
can end a level with no bugs (page 15). The "Time Bonus" is the amount 
you will earn for each day remaining on the calendar when you end a level. 
The values under the four bugs at the bottom are the amounts earned for 
trapping each one. 

The values shown on this screen increase on each level. The values for 
combining parts other than chips (like circuit boards) do not increase. See 
page 14 for these values. 



The Playing Screen 

The I. 0. Silver playing screen consists of a one-line scoreboard at the top 
and a laboratory full of chips below: 




THE SCOREBOARD 

At the top of the screen there are four indicators of the progress of the 
game at the current level: 

CALENDAR (Arcade Workshop only): On the left is the calendar. It begins 
at "JAN.01". When it reaches "DEC.31", the level ends. When you are 
zapped by a bug, the date will increase by a number of days, depending on 
which bug was the culprit (page 15). 

VACATION INDICATOR (Arcade Workshop only): To the right of the 
calendar are four small dots. These dots show how many vacations you 
have remaining in the current level (see RETURN on page 4). 
LEVEL NUMBER: To the right of the vacation indicator is the current 
level number, a colon and the number of execution points earned so far 
(page 13). 

MONEY EARNED: At the far right is the amount of money earned so far 
on the current level. It is not the total score for the whole game. That will 
be printed as "Career Earnings" in each annual report (page 16).

THE PLAYING SCREEN (continued) 



THE LABORATORY 

Below the scoreboard is the laboratory itself, a field of computer chips 
ready to be pushed and assembled by the Professor. There are three main 
things you must know about this imaginary workshop: 

■ The Professor is not strong enough to get two chips moving at the same 
time. Therefore, you cannot push a chip when there is another chip (of 
a different color) blocking it. 

■ Everything "wraps around" in every direction — the movement of the 
bugs, the chips and the Professor. Think of the screen as a flattened-out 
"sphere" if you want. This means that if you're near the bottom of the 
screen, the fastest way to the top is down. The fastest way from far left 
to far right is left. And so on. 

■ Last but not least, YOU MUST BE CAREFUL when you push a chip to 
make sure there is another one in its path to stop it. If there isn't, the 
pushed chip will keep going, wrap around the screen and CRUSH YOUR 
BODY, forcing an early retirement and ending the current level with one 
Professor down the drain. Painful and embarrassing. 



l!llJfllJiI"sriLEylLr0f[|8

D. 








If the Professor (P) pushes the chip (C) upward, 
it will wrap around and DESTROY him (D). 



10 



Moving the Professor and the Chips 

Practice makes perfect. Or so they say. You will probably learn more by 
messing around with the game than by reading this page. Read it anyway. 

KEYBOARD CONTROL 

Pressing the I, J, K or M key will cause the Professor to walk up, left, right 
or down, respectively. He will walk (or at least turn) in the direction 
selected until he runs into a chip, or until you press another direction key. 
You may press a key a little in advance of a move, and the Professor will 
remember. Sorry, no stopping between chips. 

Once the Professor has stopped at a chip, you may press the direction 
key again to push that chip (if another chip isn't blocking it). Or press one 
of the other keys (I, J, K or M) to walk (or at least turn) in another 
direction. 

If you are using an Apple like a lie or He (with a built-in repeat-key 
function), DO NOT HOLD THE KEY DOWN when you move the 
Professor. If you do, he will walk up to a chip AND push it. This is 
something you will often not want to do. All moves in this game, 
intentional or not, are irreversible. 

If you don't like the I/J/K/M configuration, change it from the main 
menu before the game starts, or by typing CONTROL-C during the game. 

JOYSTICK CONTROL 

The joystick works much like the keyboard (see above). The stick moves 
the Professor, and either button pushes a chip. Just a slight push of the 
joystick will move (or at least turn) the Professor in the direction selected. 
Once you see movement, let the stick spring back to its center position. 
Pressing either one of the buttons on the joystick will push an adjacent 
chip (if another chip isn't blocking it) in the direction the Professor is 
facing. 

If the Professor keeps going a direction you don't want him to, your 
joystick may not be centered properly. Try adjusting it by pressing 
CONTROI^C during the game. If this method fails, you'll have to use the 
keyboard. 




11 



Combining Parts 



When a level starts, the object is to combine as many same-color chips as 
possible, eventually making other "advanced parts". (Every part other than 
a chip is referred to as an "advanced part".) Ultimately, when there is only 
one shape left, you've got the Super Computer. 

Each time you combine two same-color chips into one, you earn a 
certain amount of money. When all of the chips of one color have been 
combined, they become a new part — a CIRCUIT BOARD. Circuit boards 
combine with other circuit boards and parts (but not with chips) to make 
other advanced parts, which combine to eventually make a Super 
Computer. 

You have the opportunity to build one Super Computer on every level. 
Each time you do, you will receive a Medal. Your Medals will be 
prominently displayed in the annual report and tallied on the high score 
screen.

WE REPEAT (in case you've been asleep):

ADVANCED PARTS COMBINE WITH ANYTHING EXCEPT A CHIP. 



12 



Levels and Execution Points 



When you start the game, you will play on Level 1. If you complete Level 
1, by earning enough "execution points", you will advance to Level 2 — 
starting over with a different arrangement of chips — on up as high as you 
can go (26 is the highest level, and probably impossible; let us know). 

COMPLETING A LEVEL 

To successfully complete Level number x, you must earn x execution 
points. Execution points are earned by turning one or more types of parts 
into another. For example, if you push the last two black chips together to 
make a circuit board, you will earn 1 execution point, enough to complete 
Level 1. If you build 2 circuit boards, you get 2 execution points, enough 
to complete Level 2. Creating other types of parts is worth even more (page 
14). All of these accomplishments also earn you big bucks, but money is 
not directly a factor in completing a level. 

When the number of execution points totals the current level number, 
the two numbers after "Level" at the top of the screen will match, a special 
sound will play, and you will (undoubtedly) feel a warm glow of 
satisfaction. But the level does not automatically end at this point. You 
have two options— hit the ESC key to quit the level and earn a bigger 
Time Bonus, or keep playing to build more of the Super Computer. 

Some Free Advice: Push two circuit boards together whenever possible. 
Apart they are worth 2 execution points, but pushed together (making a 
calculator), they are worth 4 points, enough to complete Level 4. This is 
much easier than trying to make 4 circuit boards. 

FAILING TO COMPLETE A LEVEL 

■ If the calendar hits "DEC. 31" before you have enough execution points, 
you will lose one of your 3 Professors and have to replay that level. IF 
you have any Professors left, that is. If you don't, the game ends. 

■ If there are no possible moves left (if there are no chips in line with each 
other and no chips can be pushed) the level ends. 

■ The worst way to end a level is by pushing a chip which is not in line 
with any other. The chip will wrap around the screen AND CRUSH 
YOU, forcing you to play that level again, regardless of the number of 
execution points earned so far in that level. Any Time Bonus or De- 
Bugging Bonus you earned will be lost. You will also lose one Professor. 
You will become depressed. 



13 



Earning Money and Execution Points 




REMEMBER: 
Just combine all of 
THE CHIPS and then all 
of the ADVANCED PARTS 
until you've got one part left- 
THE SUPER COMPUTER! 



The primary goal of I. 0. Silver is to earn money. Earning execution points 
is important too, since they let you advance to the next level, thus buying 
you more time and increasing the values for combining chips and trapping 
bugs (see next page).

The Bugs 

These are not your garden variety of crawly bugs, but the kind that prowl 
the computer world. When you are touched by a bug, you do not lose the 
game and the level doesn't end. What you do lose is time (sound familiar, 
programmers?). And your one-year deadline gets closer. 

The best defense against the bugs is to AVOID THEM. Your only anti- 
bug weapons are the chips and other parts. Smashing a bug between two 
chips of different colors will trap it temporarily. You will earn from $1,000 
to $4,000 on Level 1 for doing this kind of "error trapping". (The point 
values for the bugs, like the chips, increase each level.) However, if you 
later move either of the chips that a bug is trapped between, it will escape. 

DE-BUGGING BONUS 

Another more effective (and more profitable) way to eliminate a bug is to 
trap it between two chips of the same color. You will earn double value for 
combining the chips. Smashing two bugs at the same time triples the 
dollar value, smashing three quadruples it, and four bugs quintuples the 
money earned. Plus you also get a big De-Bugging Bonus if you can end a 
level with all of the bugs gone. But watch out — if you get zapped by a 
bug, all trapped bugs will be released. 

Bug #1: The SOFTFAIL 

Appearance: White Sparkler 
Time Lost if Zapped: One Week 
Reward for Trapping: $1,000* 

Bug #2: The INFINITE LOOP 

Appearance: Spinning Diamonds 
Time Lost if Zapped: 2 Weeks 
Reward for Trapping: $2,000* 

Bug #3: The OVERFLOW 

Appearance: Pulsating Orange Diamond 
Time Lost if Zapped: 3 Weeks 
Reward for Trapping: $3,000* 

Bug #4: The SURGE (very dangerous!) 
Appearance: Blue Lightning Bolt 
Time Lost if Zapped: 1 Month 
Reward for Trapping: $4,000* 

* Amount increases on succeeding levels

The Annual Report is a summary of how well you did on each level. Here 
is a rundown of each of the Annual Report categories: 

NUMBER OF PROFESSORS (pictured) 

The number of Professors remaining are pictured at the top right of the 
screen. At the start of the game you have 3. You lose 1 every time you do 
not complete a level. You get another Professor (up to 8 maximum) every 
time you complete an even-numbered level, beginning with Level 2. 

NUMBER OF MEDALS (pictured) 

Every time you build a Super Computer, you get a Medal. Your Medals will 
be pictured below the Professors. 

LEVEL COMPLETED 

The most recent level completed. 

EXECUTION POINTS 

This number indicates how many execution points were earned on the 
most-recent level. If the execution points are greater than or equal to the 
level number, then you have completed the level. The only exception is if 
you smashed yourself with a chip. Then you must play the level again. 



16 



PUSHES 

How many times you pushed a chip on the previous level. 
UNUSED CHIPS 

This number shows how many chips remained when the level ended. If 
you pushed all of the chips together into circuit boards, the number would 
be 00. 

BUGS TRAPPED 

How many bugs you trapped on the previous level. 
TIMES ZAPPED 

How many times the bugs got you. 
VACATIONS 

How many vacations you used. 
TIME BONUS 

This amount is earned by quitting a level with days remaining on the 
calendar. The Time Bonus begins at $250 a day on Level 1, and goes up 
$25 per day for each level. 

DE-BUGGING BONUS 

This amount is earned by ending a level with all of the bugs trapped. 
$10,000 is the reward. You get a $25,000 bonus when ALL of the bugs 
have been smashed between chips of the same color. If any bugs are loose, 
the bonus is zero. 

TOTAL INCOME 

This amount is all of the money earned on the previous level. When you 
begin the next level, this value goes back to zero. 

CAREER EARNINGS 

This amount is the sum of all earnings so far in the game. At the end of 
the first year, Total Income and Career Earnings will be the same amounts. 
After that, Career Earnings will (hopefully) be larger. 



17 



Saving Games In-Progress 

When you are in the Arcade Workshop, you can save the game in progress 
at the end of any level. You might want to do this just to take a break. Or 
you might want to go to the Strategy Lab (via the main menu) to try out 
the next level. 

IMPORTANT: DON'T SWITCH DISKS. YOU MUST SAVE 
IN-PROGRESS GAMES ON THE I. 0. SILVER GAME DISK. 

Press the ESC key when you see "Hit ESC to save game" (at the end of 
a level only). Enter your name (or any word, up to eight characters), press 
RETURN and your game will be saved to the disk. (Be sure you have a 
good, DOS 3.3, non-full, non-write-protected disk in the drive, with the 
drive door closed. If you don't, you'll get a "Disk Error" message.) 

When you want to continue a saved game, choose item 4, "See Saved 
Games", from the main menu. Enter the letter of the game you want to 
play, and you will automatically enter the Arcade Workshop. That game 
will be deleted from the Saved Game list. Of course, you can save it again 
at the end of the next level. 

A total of ten games can be saved. If you try to save an eleventh game, 
you will first be asked to select a game to be dropped from the list. If you 
don't want to lose any of the previously saved games, press ESC to keep on 
playing the current game. 

Strategy Lab Differences 

As we mentioned before, you may choose to play I. 0. Silver's "Strategy 
Lab" version by selecting it from the main menu (page 6). The Strategy 
Lab is less hectic than the Arcade Workshop. There is no calendar, no 
deadline and no bugs. You can relax and play at your own speed. Each 
level in Strategy Lab is identical to the same level number in the Arcade 
Workshop. You can plan your attack here, and then tackle the Arcade 
Workshop. Or you may want to play the Strategy Lab exclusively. A lot of 
people do. 

Before going in the Strategy Lab, type the level you want to play. You 
can choose any level from 1 to 26. You may leave the level at any time by 
pressing ESC (no execution points are needed here). 

A level will end when you press ESC, or when there are no possible 
moves left, or when you smash yourself with a chip. 

Strategy Lab games cannot be saved.

Tips on Playing I. 0. Silver 

Here are some general strategies that will help you enjoy the game, get 
higher scores, and impress your friends: 

■ DON'T PUSH CHIPS RANDOMLY. In fact, don't push a chip AT ALL 
unless it fits in with a plan of aligning and combining with other chips. 
You can't take moves back, and it's easy to get carried away trying to 
smash bugs. But you cannot complete a level just by smashing bugs; you 
must build circuit boards and earn execution points. 

■ NEVER CREATE A BLOCK OF FOUR CHIPS. The chips will become 
locked together and you won't be able to push them, making it very 
difficult or impossible to complete a level. 

■ CONCENTRATE ON CHIPS OF ONE COLOR. Decide to combine all 
of, let's say, the white chips (these have the highest point value) to make a 
circuit board. Then, take a vacation and study the screen for a new plan. 

■ WAIT FOR THE BUGS TO COME TO YOU. The best way to smash 
bugs is to find a push that helps you strategically, and wait for a bug to 
enter the line of fire. 

■ TAKE ADVANTAGE OF WRAP-AROUND. If a chip looks blocked, don't 
give up. Maybe you can move it to an advantageous position by pushing it 
in the opposite direction. 

Remember that two chips at opposite edges of the screen are actually 
touching each other. Also, don't waste time running across the screen to 
get to the other side. 

Hanging around the center of the screen will keep you from being 
attacked from the "blind side" by bugs. 

■ USE NON-VACATION PAUSES FOR LUNCH BREAKS. Rather than 
use up your valuable vacations, press CONTROL-C. This will put you in 
the keyboard or joystick adjust mode and temporarily stop the game, not 
costing any vacation time. The only problem is, you can't see the Lab. 

■ DON'T FORGET THE ESC KEY. This will quit the level when you have 
enough execution points. If the position looks bad, take the Time Bonus 
for any remaining days on the calendar. 

■ WAIT TO COMBINE PARTS. The fewer the number of parts left on the 
screen, the more difficult the game becomes. With this fact in mind, don't 
push parts together unless necessary. Just get them lined up with each 
other. When you are ready, try to make a clean sweep. Author's note: This 
is easier said than done. Good luck!

TECHNICAL STUFF ABOUT THE DISK 

The I. 0. Silver disk is a normal DOS 3.3 disk. You can boot it, catalog it 
and look at its programs to your prying heart's content. After you have 
played I. 0. Silver, however, DOS 3.3 will necessarily be rendered 
inoperable (Brad had to murder DOS to make the game fit in 48K). The 
only thing resembling a DOS command that will work is "PR # 6", which 
will reboot the disk. 

If you want to Run any of the other programs on the disk, do a fresh 
boot on the I. 0. Silver disk or any normal DOS 3.3 disk. To look at the 
I. 0. Silver game code, you'll need to move DOS to the Language Card. 
(Beagle Bros' ProntoDOS moves DOS 3.3.) 

Sorry, we can't answer technical questions about how I. 0. Silver was 
written, because we don't know. The author lives in Japan, and we'd give 
you his phone number, but (we've noticed) it's always 3 a.m. over there- 
tomorrow. 

I. 0. SILVER SOURCE CODE AVAILABLE 

If you are an advanced machine language programmer (or would like to 
become one some day) and you would like a copy of the source code for 
I. 0. Silver, mail $30.00 to Beagle Bros (address on back cover) along with 
the "Proof of Purchase" corner clipped from the back cover of this manual 
(important). 

I. 0. Silver was written with Merlin (Roger Wagner Publishing) and 
should be compatible with most other assemblers. The code occupies a 
whopping three disks (both sides) and is fully commented. There is no 
printed matter included, but you can dump the code on your printer. 
Sorry, technical questions about the program or the source code can NOT 
be answered — you're on your own.
